Challengers is an enhanced port of Kao the Kangaroo: Round 2, released a year earlier in Europe.

Kao can do many actions such as flying, throwing boomerangs, cones and other objects, swimming and skating.

Vehicles can be driven which include a snowboard, catapult, pelican, water barrel and motor boat.

There is also a multiplayer mode where players can use 15 different weapons including bombs, fire flamer and a magneto.

[2] The sequel to this game and Round 2 was titled Kao the Kangaroo: Mystery of the Volcano, and was released for the PC in 2006 exclusively in some non-English countries, serving as the character's swan song until 2022, when the series was rebooted.
